Abstract

A hermetic compressor with an improved operating efficiency for use in a cold storage, freezing chamber or the like, in which a suction pipe (23) is located with its one end (23e) in the vicinity of an inlet opening (22) of a suction muffler (17) so that heat of a closed casing (1) is not easily transmitted to the suction pipe (23) for less heating of the cooling medium gas drawn in, and thus, cooling efficiency is improved by preventing discharge of the low density cooling medium into the cooling system through compression of the expanded cooling medium gas.
